New Guinea Impatiens plant named ‘Balcebpurs’

ABSTRACT

A new and distinct New Guinea Impatiens cultivar named ‘Balcebpurs’ is provided. This new cultivar was the result of a controlled irradiation program. More specifically, cuttings from ‘Grape Crush’ were irradiated with 2 kilorads of gamma rays and allowed to grow. One of the cuttings was discovered to exhibit a flower with petals having a distinct striping pattern and was allowed to continue to grow. The resulting plant exhibited a number of flowers having petals which exhibited the same striping pattern. This cutting/plant was designated BFP-1865.

The present invention comprises a new and distinctive New Guinea Impatiens plant, hereinafter referred to by the cultivar named ‘Balcebpurs’.

The new cultivar is the product of a controlled irradiation program. More specifically, cuttings from ‘Grape Crush’ (U.S. Plant Pat. No. 10,107) were irradiated with 2 kilorads of gamma rays and allowed to grow. One of the cuttings was discovered to exhibit a flower with petals having a distinct striping pattern and was allowed to continue growing. The resulting plant exhibited a number of flowers having petals which displayed the same striping pattern. This cutting/plant was designated BFP-1865. Asexual reproduction of the new cultivar by terminal or stem cuttings taken during 1998 and 1999 at Arroyo Grande, Calif., U.S.A. has demonstrated that the characteristics of the new cultivar as herein described are firmly fixed and are retained through successive generations of such asexual propagation.

SUMMARY OF THE INVENTION

It was found that the cultivar of the present invention:

(a) Exhibits attractive large round flowers with distinctive striping pattern,

(b) Forms medium green foliage,

(c) Exhibits a good basal branching character.

The ‘Balcebpurs’ cultivar has not been observed under all possible environmental conditions to date. Accordingly, it is possible that the phenotype may vary somewhat with variations in the environment, such as temperature, light intensity, and day length.

When the new cultivar of the present invention is compared to Grape Crush, it is found to be substantially identical in growth habit, form and size. However, the flower color is distinctly different. The flower color of the new invention exhibits a background color of Red-Purple Group 74A with stripes of Red-Purple Group 65C (adaxial) and Red-Purple Group 74B (abaxial) whereas ‘Grape Crush’ flowers are Red-Purple Group 74A with the lower four petals commonly displaying bases of 53C (abaxial) and Red-Purple Group 74B (abaxial).

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photographs show as nearly true as it is reasonably possible to make the same in color illustrations of this type, typical flower and foliage characteristics of the new cultivar. The plants were grown in a greenhouse at Arroyo Grande, Calif., United States of America.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of colors described herein is The R.H.S. Colour Chart of The Royal Horticultural Society, London, England. The color values were determined on Oct. 8, 1999 in West Chicago, Ill. The readings were taken between 1:00 and 1:45 p.m. under approximately 2500 footcandles of light. The plants were produced from cuttings taken from stock plants and were grown under greenhouse conditions comparable to those used in commercial practice while utilizing a soilless growth medium and maintaining temperatures of approximately 72° F. during the day and approximately 65° F. during the night. The plants used for the following measurements and descriptions were grown for twelve (12) weeks from rooted cuttings.

Propagation:

Type cutting.—Terminal tip.

Time to initiate roots.—Approximately 14-21 days with the shorter times generally being experienced in the summer and the longer times in the winter.

Flower description:

Flowering habit.—‘Balcebpurs’ is freely flowering under outdoor growing conditions with substantially continuous blooming from spring until fall.

Flowering borne.—Above foliage arising from leaf axils.

Peduncle length.—6.1 cm.

Peduncle color.—146C overlaid with 183D.

Flower form.—Single.

Quantity of flowers.—Approximately 3 per lateral branch.

Flower size.—Approximately 5.9 cm in diameter.

Number of petals.—Five.

Petal texture.—Smooth.

Petal shape.—Obovate.

Petal base.—Lower petals are narrow, upper petal has broad base.

Petal length.—3.3 cm.

Petal width.—3.5 cm.

Flower color.—The petals are Red-Purple Group 74A with stripes of Red-Purple Group 65C (adaxial); Red-Purple Group 74B (abaxial). The petals of ‘Grape Crush’ are Red-Purple Group 74A with the lower four petals commonly displaying bases of Red Group 53C (adaxial); Red-Purple Group 74B (abaxial).

Flower bud shape.—Elliposoidal.
